Applications of Supercritical Fluid Extraction (SFE)

The extraction of polysaccharides utilizing SFE is a research area of great interest. One of the main focuses of the current research is to optimize the SFE parameters to improve the efficiency and purity of polysaccharides. The impact of the type of supercritical fluids (SCFs) used on extraction efficiency and product quality is currently being investigated. In addition, researchers are studying the selectivity of SCFs for specific types of polysaccharides. Different SCFs have varying solubilities or affinities for various polysaccharides, thus allowing target compounds can be selectively extracted. This selectivity can be further improved by changing the process conditions to favor the extraction procedure. In a word, polysaccharide extraction using SFE techniques is progressing. It selectively extracts desired compounds without harsh solvents ensuring higher purity and minimizing compound degradation SCF extraction also removes residual solvents from finished pharmaceutical products polymer processing.

SFE Service at CD BioGlyco

At CD BioGlyco, we have advanced technologies and our scientists are experienced and knowledgeable in SFE. We strive to provide our clients with satisfactory and quality Polysaccharide Extraction services from a range of sources using SFE. The process of our service is described below:

• The samples containing the target polysaccharides are prepared and the samples are subjected to preliminary treatment to remove impurities, break cell walls, and other operations.
• Suitable SCFs are selected. Optimization experiments to determine process parameters for SCFs that have a significant impact on extraction effectiveness and selectivity.
• Load the pre-treated sample into the SFE device and heat and pressurize the SCF to a supercritical state. The length of the extraction time will affect the extraction effect, and the reaction time is adjusted as needed.
• The collected product solutions are further processed and purified.
